Question

Write the skeleton equation for the following word equation and then balance them. 

1. Carbon + Oxygen → Carbon dioxide 

2. Phosphorus + Chlorine → Phosphorus pentachloride. 

3. Sulphur + Oxygen → Sulphur dioxide 

4. Magnesium + hydrogen chloride → Magnesium chloride + Hydrogen

Answer 1

Balanced equation: 

1. C + O₂ → CO₂ 

2. P₄ + 10 Cl₂ → 4PCl₅ 

3. S + O₂ → SO₂ 

4. Mg + 2HCl → MgCl₂ + H₂

Skeleton equation:

1. C + O₂ → CO₂ 

2. P + Cl₂ → PCl₅ 

3. S + O₂ → SO₂ 

4. Mg + 2HCl → MgCl₂ + H₂
